Converter sludge, a byproduct produced on large amounts in the steel making process, is an important resource that can be utilized effectively. This paper describes an experiment in which converter sludge was tested as an adsorbent for the removal of phosphorus from waste water. It was found that the phosphorus removal depended on the amount of converter sludge added, the pH value and the contact time. Under laboratory conditions when the added sludge was 2. 0mg/100ml, the contact time 4h and the pH value of equalized 4, over 88% of phosphorus was removed; the experimental data on converter sludge adsorption of phosphorus in the water fitted the Freundlich isotherm model. Converter sludge was found to be very effective in adsorbing the phosphorus. 相似文献

借助于热重分析与光学显微镜观察,测定了含钛磁铁矿在700~1000℃温度范围氢还原速率,并与铁的氧化物的氢还原进行比较,结果表明钛磁铁矿氢还原时的有效扩散系数De较铁氧化物氢还原时的De低,说明含钛磁铁矿较铁的氧化物难还原。 相似文献
